(FARMERSBURG) - The Sullivan County Sheriff's Office, along with investigators from the Indiana State Police continue to seek the person responsible for the 1981 murder of 51-year-old Jeanette Benson of Farmersburg.

According to police reports, on January 2, 1981, Jeanette Benson had returned from Terre Haute where she had been grocery shopping to find an intruder inside her home. Jeanette's husband Emory, was at work in Terre Haute at the time.

Sheriff Clark Cottom says two neighbors describe seeing a "robin egg blue" four-door possible Plymouth Valiant, parked in the Benson's driveway just prior to Mrs. Benson returning home. The vehicle was missing its hubcaps. Another said the vehicle was medium size with "shiny" blue paint.

A resident in the area told police the white male in the vehicle was tall, thin and possibly in his 20's - at the time and believed to have been wearing a vest. Sheriff Cottom says the murder suspect would now be in his 50's.

The man was seen exiting the vehicle and knocking on the Benson's front door.

Sheriff Clark Cottom is hopeful that sharing this information may spark someone's memory and help investigators solve this murder.
